I, as shown in "Fig. 4", the enamel control method of the flat display device of the present invention is used to test the screen state by using a round-robin test on the sample display of the sample display device, such as a camera for a front panel defect. (S1). In step S1 of the image quality control method for plane spoofing according to the embodiment of the present invention, the input signal of the flat display device can be increased from the lowest gray level (4) to the gray level, and (white) one by one gray scale, and the instrument is analyzed by the instrument. The phase 8 of the flat display device sample shows the displayed image of the sample. For example, 'for a flat-panel display device with a resolution of 1366 768, each red (R) green, ((blue (B)) sub-pixel receives an 8-bit input in the image quality control method of the embodiment flat display device. Signal, and from 〇 grayscale to ^ screen 256 times. And, the resolution of each test is (4) X, s, greater 'party degree is at least 8 bits or more resolution. As a result of the test, the image quality control method of the solid-filled flat display device of the present invention can determine that the bribe is in the face of the gambling. If the flat-paste product is 1345187 100 years, 2^25 days for the drag defect, the embodiment of the present invention displays the plane. The (4) enamel control value is corrected to correct the panel _ 赖 色 chromatic aberration, and then the input view data is adjusted according to the compensation value to compensate the brightness or chromatic aberration at the panel defect position (S2). In step S2, the embodiment of the present invention is flat. The quality control method of the display device can obtain the position and extent of each button defect in each step from the test result of step S1, and then determine the compensation value. Since the brightness or chromatic aberration according to the panel defect is not uniform, it should be optimized. Each panel is missing The compensation value at the trap position, and considering the gamma characteristic shown in Fig. 5, the compensation value for each gray scale should also be optimized. Therefore, the compensation value should be set for each gray scale, or As shown in Figure 5, the compensation value is set for each gray-scale area (A, B, c, D) composed of multiple gray levels. For example, the compensation value should be the optimized value of each position, that is, " panel defect 设置 is set to "+1〃' is set to 〃 at panel defect 2, set to , at the 缺陷 panel defect 3〃, etc. In addition, the compensation value can also be for each grayscale The optimized value of the zone setting, that is, in the grayscale zone, is set to "〇〃, in the / grayscale zone Β" is set to "〇〃, in the grayscale zone C〃 is set to 〃 I〃, set to 〃丨〃 in the gray level area D〃. Therefore, the compensation value of each gray level in the same panel defect can be different. Each red 'green, k color sub-unit of a single element The compensation values of the prime data are set to be the same, so the compensation value should be the setting of each pixel containing red, green, and blue sub-tendin. In addition, when correcting the color difference The compensation value of each red, green, and blue sub-enrichment data is different. For example, if the defect area of a special panel is more red than the non-defective area, the red sub-tenk compensation value will be less than green and blue.
